I am trying to use 2 threads. 1 thread prints only odd number and the other thread prints only even number and It has to be an alternative operation.
Eg:
Thread1 1
Thread2 2
Thread1 3
Thread2 4
and so on..
Below is the program, please let me know where I am going wrong as the thread1 is not coming out of wait state even when the thread2 is notifying it..
public class ThreadInteraction {
public static void main(String[] args) {
new ThreadInteraction().test();
}
private void test() {
ThreadA ta = new ThreadA();
Thread t = new Thread(ta);
t.start();
try {
Thread.sleep(1000);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
for(int i=2;i<=50;){
System.out.println("Thread2 "+i);
synchronized (t) {
try {
t.notify();
t.wait();
} catch (Exception e) {
e.printStackTrace();
}
}
i=i+2;
}
}
}
class ThreadA implements Runnable{
@Override
public void run() {
for(int i=1;i<50;){
System.out.println("Thread1 "+i);
synchronized (this) {
try {
notify();
wait();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
i=i+2;
}
}
}
